Last year, Trump fired FBI director James Comey, leading to Mueller’s appointment.

Special counsel Robert Mueller wants to talk to President Trump about his firing of former FBI director James Comey and disgraced national security adviser Michael Flynn, according to a report on Tuesday.

Attorney General Jeff Sessions was questioned last week by investigators working on Mueller’s Russia probe, the Department of Justice confirmed on Tuesday.

Sessions’ sit-down marks the first time that a member of Trump’s cabinet has been questioned in the investigation into Russian meddling in the 2016 election and the possibility that Trump’s campaign coordinated with the Kremlin.

Sessions was joined by lawyer Chuck Cooper when he met with Mueller’s team, according to the New York Times, which first reported the interview.

The federal investigation is reportedly looking into the finances of several of the President’s associates and whether the Trump obstructed justice in firing Comey and Flynn.

The President publicly berated Sessions following Mueller’s appointment, tweeting out his disappointment and telling the press he wouldn’t have chosen Sessions had he known he would recuse himself.

The nation’s top prosecutor's decision to step away from the probe came after questions were raised about his foreign contacts during the campaign.

The early Trump supporter, at the time an Alabama Senator, met twice with the Russian ambassador to the U.S. during the campaign, something he failed to mention during his confirmation hearings or in testimony before Congress.
